RETAINER FOR ROLLER THRUST B EARINGSQ =-Application filed .l'uly 15. 1918. SerialNo. 244.957.

7 '0 all whom it may concern:

Be it known that I, EDwIN E. ARNOLD, a

" nular and will extend around the bore of citizen of the United States, and a resident of, Pittsburgh, in the county of Allegheny and State of Pennsylvania, have made a new and useful Invention in Retainers for Roller Thrust-Bearings, of which the following is a specification.

This invention relates to anti-friction bearings, and more particularly to retaining and spacing means for the anti-friction In the drawings accompanying and forming a part of this applicatlon and throughout which similar elements are denoted by like characters, Figure 1 1s a fragmentary view of a device embodying this invention; 1n one portion of the view the device is-illustrated in completed form and to. Fig. 1 but instead of balls as employed .in Fig. 1 for the..a1'iti-friction members rollers are employed. Fig. 5 is a view in sectional elevation taken through the rein the other in partially completed form. Fig. 2 is a view in sectional elevation of a retainer embodying this invention showing the same partially completed. Fig. 3'is a similar View to Fig. 2, showing the retainer fully'j.-.completed. F ig. 4 is a view similartainer shown in Fig. 4; with a pair of the rollers in place. Fig. 6 1s a cross sectional tering view of the portion of the retainer shown in Fig. 4 partially completed and Fig. 7 is a view similar to Fig. 6 but with the ietainer completed.

In carrying out this invention an annuiar disk or plate 8 is preferably .die cast from suitable malleable metal in such manner that pockets9 are formed for the reception of the anti-friction balls 10 or for the reception of the anti-friction rollers as the case may be. These holes are suitably arranged and spaced apart one from the other as is now common. I

The late in thickness is less in diameter "than t e anti-friction members so that Y ledges 11. When the friction members-com sist of'balls these ledges or lips will be anthe pocket and project inwardly so asto reduce the opening to the ocket on that side of the. plate or disk. l hen the anti-friction member is a roller there will be two lips or ledges 1-2 for each pocket, each projecting inwardly from one longitudinal side of the pocket. I

The opposite side of the plate or disk is provided with a mass of metal in the form of a ridge or lip located adjacent the pockets and projecting beyond the normal face of the plate or disk and this metal'i s adapted to. be forced into the'pockets to form retaining lips. In the case of balls I the mass of metal will be in the form of an annular lip .13,'Fig. 2, surrounding the ball pocket and in the case of rollers lips 14 projectabove the normal face of theplate along each longitudinal edge of the roller pocket as shown in Fig. 6.

After the anti-friction devices have been assembled in the disks or plates a filled plate is placed between con'iplementary sides 15, carried in a suitable pressand provided with clearance pockets 16 'regiswith the anti-friction; members. These pockets are of such shape and form as to c ear the anti-friction members While they force the metal of the lips or ledges into the pockets as shown at 17, Fig. 6, and-- 18, Fig. 7. The anti-friction members are thus securely retained in place.

Retainers for anti-friction bearings in some respects similar to this have hereto fore been manufactured but in those with which I am familiar no projecting lip or- ]edge was provided but the retaining lip corresponding to lips 17 and 18 was derived from the (plate itself and spun into the pocket an this procedure necessitated a spinning "operation for each individual pocket while with my invention all of the retaining lips for a single retainer may be i formed in one and t e same operation thereby materially reducing the expense.

and increasing the speed of manufacture Iclaim is- 1. A cage foranti-friction bearings comprising anannular member of malleable metal having openings extending "there-- through ,withthe area or saidppenings on.

i one side less than on the other side and ridges adjacent said last mentioned openings and projecting beyond the normal face of said member on the opposite side thereof from the smaller openings. said ridges being adapted to be forced into the adjacent openings to reduce the area thereof to retain the anti-frictional bearings.

2. The method of providing a plate retainer 'for end thrust ball bearings with balls.

lockedtherein, which consists in forming a plate froin inalleable metal having holes extending therethrough from side to side, said holes on one side being of less diameter than on the other and said plate on the side on which the holes are of greatest diameter being provided with annular-lips or ridges I extending beyond the normal plate plane, of placing balls in said pockets and then in applying pressure to said lips or ridges whereby the metal thereof is caused to flow into said pockets so as to decrease the diameter of the pocket openings on that side of the plate.

3. A cage for anti-friction bearings provided with bearing pocket leaving a retaining lip at that end of the pocket, each of said pockets being provided with a flange extendinr beyond the normal face of the opposite Sl( e of the cage and adapted t0.be compressed about the edge of its respective pocket to retain a bearing inserted therein.

4. A plate retainer for end thrust bearingsv provided with pockets for anti-friction memers and having lips of metal projecting beyond one normal face of the retainer adapted to be forced into said pockets to form retaining lips for anti-friction elements inserted within said pockets.

5. A retainer for end thrust bearings, comprising an annular plate or disk provided with a series of pockets for anti-friction members and having a body of metal adjacent each pocket and projectin beyond one normal face of'said plate or dis and adapted to be distorted to form an inwardly projecting retaining flange for said pocket, each pocket adjacent the other face of said plate or disk-being provided with an inwardly projecting retaining flange.

6. The method of providing a retainer for anti-friction bearings, which consists in forming an annular member of malleable metal having holes extending therethrough from side to side, said holes in one side being of less diameter than in the other and said annular member on the side on which the pockets, each of said pockets'having a hole leading into it fronr one side of the cage of less diameter than the holes are of the greatest vided with annular lips or ridges extending beyond the surface thereof, of placing antifriction rolling members in said pockets and then in applying pressure to said lips or ridges whereby the metal thereof is caused to flow into said ockets so as to decrease the size of the poc iet openings on that side of said member.

7. A cage for anti-friction bearings'provided with bearing pockets, each pocket having a hole of less diameter than the pocket leading into it from one side of the cage and leaving a bearing retainin lip at that end of the pocket, the other sid e of the cage being provided around each flanges projecting beyond the normal plane of that side and adapted to be distorted to form bearing retaining lips.

S. In a cage for anti-friction bearin s, a pocket having a hole leadinginto it from one side of the ca e of less cross sectional area than the poc et and rovidin a retaining flange at-that end of the poc et, the opposite side of said cage with a flange surrounding said pocket and extending outwardly beyond the normal face of the ca e side bearing element'to said pocket and to be compressed to the level of said side and form a retaining lip for an admitted bearing ele-:

ment.

pocket with being provided diameter being pro- I,

9. The method of providing retainers for anti-friction bearings with the same located therein, which consists in forming a cage from. malleable metal having holes extending therethrough, said holes in one side being of less area than in the other and said cage on the side in which the holes are of the est area being provided with lips or ridges extending beyond the normal cage surface,

of placing bearings in said pocketsand then in applying whereby the metal thereof is caused to flow into said pockets so as to decrease the area of the pocket openings in that side of the cage.

10. An anti-friction bearin leable material provided witi bearing receiving openings, each opening extending through a continuous and integral portion of the material of said cage and having hearing retaining ridges at the ends thereof, the outer surfaces of each ridge being continuoils with and a part of the cage surface interrupted by its 0 ening.

In testimony w cage of maliereof, I have hereunto subscribed my name this 3rdday of July. 1918.
